SUPPLEMENTARY-LENS MOUNTING FOR SPECTACLES 0R EYEGLASSES.

SPECIFICATION forming part of Letters Patent No. 716,194, dated December16, 1902-.

Application filed April 11, 1902.

To all whom it may concern:

Be it known that I, LYDIA A. CONN, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certain 5ImprovementsinSupplementary-LensMountings for Spectacles and Eyeglasses,of which the following is a specification.

The object of my invention isto so construct a supplementary-lensmounting for spectacles or eyeglasses that the same will be of a cheapand simple character, will be out of the way when the lenses are in use,and will permit of the application or removal of the supplementarylenses by simply dropping the mounting onto or lifting it from thenosepiece of the ordinary spectacles or the springposts of theeyeglasses.

In the accompanying drawings, Figure 1 shows a pair of half-lensesprovided with a mounting in accordance with my invention for applicationto a pair of spectacles, and Fig. 2 is a view of the pair of spectacleswith the supplementary lenses mounted thereupon.

. The lenses 1 are connected by a nose-piece 2, secured to said lensesby clips-3 of the ordinary character, and from each of these clipsprojects inwardly a bar 4, terminating at its inner endin alaterally-bent hook 5 at the bottom, the free member of saidhook beingsomewhat longer thanthe member which is connected to the bar4: and beingalso bypreference curved laterally to the right in the case of aright-hand hook and to the left in the ]z?ase of a left-hand hook, asfully shown in In applying these supplementary lenses to the ordinaryspectacles the hooks 5 are simply dropped onto those portions of thenosepiece which extend from the bow to the frames, as shown in Fig. 2,the hooks snugly fitting these portions of the nose-piece, so as toprevent lateral movement of the supplementary lenses in respect to themain lenses, 1 while confinement of the frames of the spectacles betweenthe hooks 5 and clips 3 prevents any movement of'the supplementarylenses toward or from the main lenses.

Removal of the supplementary lenses can be efiected by simply liftingthem so as to free the hooks 5 from engagement with the nose-piece. Inconstructing the supplementary-lens mounting for application to eye-Serial No. 102,422. (No model.)

glasses a spring will be used in place of the rigid bow 2, and the hooks5 will be so formed as to engage with the spring-posts or otherconvenient portion of the lens-mounting.

A mounting for supplementary lenses such as I have devised is entirelyout of the Way when the lenses are in place and is therefore not open tothe objection of a mounting which engages with the temples of thespectacles, andthe supplementary lenses can be more readily applied orremoved than if they were provided with laterally-yielding spring-jawsfor engaging with the inner portions of the spectacle-frames, as suchlaterally-engaging jaws require the employment of an elastic nose-piecein connection with the supplementary lenses, so that they can be movedtoward each other in order to clear the frames of the spectacles andthen permitted to expand in order to engage said frames. Besidespermitting more ready application or removal of the supplementary lensesmy improved mounting is of simpler and cheaper character than one suchas I have just described.

The lengthening of the free member of the hook and the lateral bendingof the lower end of the same serve to guide the supplementary mountingto its proper place upon the nosepiece, and thereby facilitate theapplication of the same.

Having thus described my invention, I claim and desire to secure byLetters Patent 1. A supplementary-lens attachment for spectacles oreyeglasses, consisting of a supplementary-lens mounting and a pair ofhooks projecting therefrom, and disposed so as to vertically engage thenose-piece or other central portion of the main-lens mounting,substantially as specified.

2. A suppleinentarylens attachment for spectacles or eyeglasses,consisting of a supplementary-lens mounting and a pair of hooksprojecting therefrom, said hooks being open at the bottom, and the freemember of each hook being carried downwardly beyond the other member,substantially as specified.

3. A supplementary-lens attachment for spectacles or eyeglassesconsisting of a supplementary-lens mounting and a pair of hooksprojecting therefrom, said hooks being open at the bottom, and the freemember of each hook being carried downwardly beyond the other member andbent laterally at its lower end, substantially as specified.

4. A supplementary-lens attachment for spectacles or eyeglassesconsisting of a supplementary-lens mounting and a bar projectinginwardly therefrom in a direction substantially at right angles to theplane of the lens, said bar terminatingin a laterally-bent hook open atthe bottom, substantially as :0 specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

LYDIA A. CONN.
